Recomended by speedwerx for their 0 to 5000 m8 pipe is a power commander. I kinda know why but what exactly goes wrong and when. This would help in tuning. Why does slp,s set up not in need of more fuel. I have speedwerx pipe and feel that i have lost power but use a power commader v with their tune. I have a friend with same stock sled that has more get up and go. Kinda embarasing spending all that money to get beat. Ii must be doing something wrong.
